Can someone help me interpret this dream....?

So in the dream I was with vampires, a man who was my grandfather and two children I was related to. We were heading to a forest to search for this legend woman who had apparently died there. In the dream they had to combine our blood to make me a vampire (and I was doing this willingly). But even though we had books on her and her life we didn't know the spot in which she died and thus never found her. There was also a scene that focused on this lime-green crocodiles. Can anyone help me work this one out... its really affected me in the morning.
